Thanksgiving 2017: Chicago Airports Among Most Delayed

CHICAGO, IL — For the many Illinois residents with flights booked for what is expected to be a record Thanksgiving weekend at O'Hare and Midway airports, officials have some tips to keep the hassles to a minimum. This Thanksgiving season, an estimated 4 million will fly, a 5 percent increase over last year, according to AAA. Chicago's airports are among those with the most delays during the holiday travel season.

A new report from RewardExpert found that during the five days before and after Thanksgiving, around 20 percent of flights are delayed at O'Hare International Airport, which is among the busiest airports in the world. Midway didn't fare much better, with 19.6 percent of flights delayed. The study took a look at the 45 busiest airports in the U.S. and found that the Windy City airports were among the worst when it comes to delays.

But it wasn't all bad news for Chicago's airports. RewardExpert found that both airports had a bump in on-time flights last Thanksgiving, with 3.26 percent fewer delayed flights at Midway. O'Hare's on-time flight average jumped from 79.94 percent in 2011-2015 to 81.29 percent last year.

The study also found that the best airport for those looking to avoid delays is Honolulu, where 91.48 percent of flights are on time. The worst airport for delays is in San Francisco, with an on-time flight average of 75.47 percent.

Nationwide, the busiest travel days will be Nov. 21 and 22, the Tuesday and Wednesday ahead of Thanksgiving and Nov. 26, the Sunday after Thanksgiving, says Lisa Farbstein, acting director of media relations for the Transportation Security Administration. Thanksgiving will be the lightest travel day if you still need to book a flight. Airlines are adding flights to accommodate the large number of travelers during the Thanksgiving period.

According to RewardExpert, the best day to fly out of O'Hare and avoid delays is Nov. 24, the day after Thanksgiving, and the worst is Nov. 27. At Midway, Thanksgiving Day is the best day to catch a flight, and, like O'Hare, the worst day is Nov. 27.

To help reduce delays, here are some tips for airport travelers, courtesy of the TSA:

Plan Before You Go

• Pack smart – Know your airline’s checked bag policies and fees, remember not to pack laptops and other devices with lithium ion batteries in your checked bags, leave gifts unwrapped and pack liquids you plan to carry-on with you according to the 3-1-1 rule.
• Check with your airline – Confirm your flight status and gate location before departing for the airport, and make sure you’re aware of airline policies regarding check-in times, boarding processes, fees and rebooking options.
• Leave early – Allow for extra time getting to and through the airport, as holiday travel can cause backups on roadways and longer passenger queues throughout the terminal. Experts recommend arriving at the airport at least two hours before domestic departures and three hours before international departures.

Minimize Your Wait

• Prepare for new screening procedures – The TSA is implementing new screening procedures which require passengers to remove electronic devices larger than a cell phone from carry-on baggage. The TSA also recommends placing food items in bins for easier screening. Pack your carry-ons accordingly by putting items like electronics, toiletries and food in easily accessible places.
• Enroll in a trusted traveler program – Trusted traveler programs like TSA Pre✓® and CLEARprovide passengers an easy alternative to standard screening procedures and speed-up the security screening process. If traveling abroad, consider enrolling in Global Entry or using Mobile Passport to expedite Customs processing upon your return.

General Airport Tips

• Re-confirm the status of your flight with your airline before arriving at the airport.
• Expect full flights and full luggage bins on board.
• Bring government-issued I.D. for all adult travelers and passports for all travelers on international trips.
• Keep valuables out of plain sight and pack them in carry-on luggage only. Remember to lock cars and take the key.
• Leave gifts unwrapped until after the flight. Review TSA's prohibited items list.

The Transportation Security Administration says these are the peak travel times with the longest waits:

• Saturday, 6 to 8 am and 1 to 2 pm
• Sunday, 6 to 8 am and 4 to 7 pm
• Monday, 5 to 8 am and 3 to 6 pm
• Tuesday, 6 to 8 am and 3 to 5 pm
• Wednesday, 6 to 8 am and 4 to 5 pm
• Thursday, 5 to 8 am and 4 to 7 pm
• Friday, 5 to 8 am and 3 to 5 pm

Travel booking website KAYAK has a feature on its app (for both iOS and Android devices) that lets you check the estimated security line wait times, which is collected through real-time feedback from app users and the TSA website.

To help speed the security screening process, travelers should arrive early at the airport, authorities say, preferably two hours ahead of a domestic flight and three hours before an international flight to ensure they have time to park or return rental cars, check their bags, get a boarding pass and hit the restroom — all before heading to the security checkpoint.

But it's more than about arriving early. You should also prepare ahead of time by following the 3-1-1 rule: when packing toiletries, have no more than 3.4 ounces of liquid in a 1-quart plastic bag, and no more than one bag for every person.

Wear shoes that are easy to get on and off as you go through security screening. Empty your pockets before heading through the checkpoint screening equipment. Also, make sure you don't have any prohibited items.

"The most common mistake that passengers make is that they have items that are prohibited at a checkpoint—mainly oversize liquids and various knives that are in their carry-on bags," the TSA says. "Prohibited items detected at a checkpoint will slow a checkpoint line. They require bag-checks, tests for traces of explosives and finally, rescreening through the X-ray equipment and can add a few minutes to the amount of time it takes an individual to complete the screening process."

Travelers are encouraged to follow these tips:

• Prepare for security when packing. Put large liquids, gels, creams and aerosols into checked bags -- think shampoo, conditioner, suntan lotion, shaving cream and anti-perspirant. If you've only got a carry-on bag, make sure all of your liquids follow the 3-1-1 rule.
• Follow 3-1- 1 liquids rule for your carry-on bag. Liquids, gels, aerosols, creams and pastes must be 3.4 ounces or less and all bottles must fit in a single quart-size plastic bag and placed in a bin for screening. This includes sun block and tanning sprays. Let the TSA officer know right away if you're traveling with larger quantities of medically-necessary liquid medications or breast milk or formula for an infant.
• Documents ready: When you enter the checkpoint line have an acceptable ID and boarding pass out of your wallet and ready to hand to the TSA officer. Once you get to the screening tables, remove large electronics including laptops and the 3-1- 1 liquids bag, from carry-on baggage.
• Less accessories: Consider minimizing items that you wear to the airport such as bulky jewelry, scarves, hair accessories, large belts and other bulky items that are likely to require additional screening. Remove all items from your pockets and put them into one of your carry-on bags so you won't lose them.
